DMA-8X8
2. Overview
2.1. Introduction
The DMA 8X8 is equipped with several core technical features to facilitate the work of audio engineers.
DSP-based remote audio equipment is routed, processed and controlled by computer.
The Tecnare DSP Controller is a Windows-based application, which is used to conduct conguration
and control of DSP hardware. DSP Controller has 16 built-in presets, and the modules and sequences for each pre-
set can be exibly designed in accordance with the designer’s requirements. After the design is nished, it can be
saved for future use. The sequences and parameters of DSP Controller’s built-in processing modules accord to most
of the application scenarios without any change.
DSP Controller is a full-featured application, including the parameter adjustment and peripheral acces-
sory settings of all modules, such as RS232, RS485, click-and-drag panel conguration and optional Dante network
audio control. The most interesting part is the user interface, which allows the engineer to customize user interface
so that the Integrator can edit it or the on-site technicians or end users who have no idea of relevant techniques can
operate it. Superior safety functions make it possible for the end users to access to the controls allowed by the engi-
neer or designer.

3.2. Audio Output Connections
The rear panel of DMA 8X8 o󰀨er 8 balanced analogue MIC/LINE inputs. It features a couple of re-
movable balanced 12 pin Phoenix terminal strips.
Unit gain (0dB) is set through volume control, and the analogue output section is corrected to +4dBu
with 20dB headroom. That is to say, 0dBFS digital signal is equivalent to +24dBu output signal. If other signal levels
are required, you may change the volume to achieve it.
3.3. Audio Wiring Reference
• Balanced Connection
The HOT, + or ‘in phase’ connection should be made to pin + on the terminal strips or pin 2 of the
XLR connector.
The COLD, - or ‘out of phase’ connection should be made to pin - on the terminal strips or pin 3 of
the XLR connector.
